The research tradition within the Human Behavior and Design major is based on the social sciences, in particular environmental psychology and human factors and ergonomics. The underlying premise is that systematic, empirical research based in the social sciences, when combined with an understanding of design processes, can contribute to the planning, design, and management of environments that enhance individual and organizational effectiveness.

Program Focus

The Ph.D. in Human Behavior and Design at Cornell University is a multidisciplinary program integrating the social sciences and design. Research focuses on environmental settings across a range of scales (from products to buildings to cities), that support safe, healthy and productive behaviors and foster sustainable design and lifestyles.

The program brings together faculty and students with expertise in the fields of interior, industrial and graphic design, architecture, art, design history, historic preservation, design with digital media, building technology, environmental psychology, human factors and ergonomics, economics, and facility planning and management to work on problems related to the interior environment.

The Ph.D. in Human Behavior and Design rests on the following basic premises:

  • Development of the knowledge base guiding the planning, design, and management of physical settings requires systematic, empirical research.
  • The physical environment affects the realization of human and organizational potential including health, safety, comfort, productivity and satisfaction.
  • The users of environments are diverse and have different needs. Individual characteristics such as culture, gender, stage in the life course, family structure, role or task affect environmental needs.
  • Organizational culture, goals, and structure help shape building design and use.
  • The planning, design, and management of good environments require consideration of all users.
  • Understanding organizational and human needs is no less critical than understanding financial, technological and aesthetic factors influencing the planning, design, and management of our physical surroundings.
  • Multidimensional spatial experiences are heightened through an understanding of design elements, such as circulation, materials, lighting and acoustics.
  • Theory provides a foundation that both informs and is informed by research and practice.

The program draws its strength from faculty knowledge and research in the following four areas:

  • Design
  • Environmental Psychology
  • Facility Planning and Management
  • Human Factors and Ergonomics

Ph.D. Requirements

Ph.D. in Human Behavior and Design curriculum requirements and the graduate student handbook.

People who embrace thinking across disciplinary boundaries and who have a passion for teaching and scholarship are encouraged to apply. The strength of this unique new program is the integration of scientific and creative expertise within the same department. Applicants' prior disciplines might include (but are not limited to): social science, design, or engineering.

Prospective Ph.D. Student Application Requirement FAQ

First, you should read papers written by faculty with whom you might like to work to see if your interests align. Carefully review the websites and online materials provided by the program. In your application, describe your experience related to research, statistics, design, etc. Demonstrate your research experience. Describe you interests – possible dissertation research directions. Indicate your goals following the PhD. Request letters of recommendation from people who can speak to your research aptitude, commitment, preparedness, work ethic.

Yes, the Graduate School can help with this, but you must still adhere to our requirements and deadlines. 

No, we only have one admission cycle, applications are due in November for PhD; students start in the Fall semester of the following year.

All application materials are submitted online via the Graduate School’s application system (available on the web at: 

No, a portfolio is not required for the Ph.D. degree.

No, but scholarly writing sample submissions are preferred (ex: Master’s Thesis; Peer Review Journal Article; Senior Honors Project).

HCD provides four years of funding to Ph.D. students in HBD, as long as students’ progress and performance is satisfactory. This funding could take the form of teaching assistantships, research assistantships, fellowships, or some combination and is typically for the nine-month academic year.

No, it is not necessary to have an MS or MA before beginning the PhD.  The strongest applicants are those who have a foundation in research (e.g., have completed a research thesis (undergrad or graduate), have participated in a lab as a research assistant, have perhaps taken a social science research methods class).

For the PhD in Human Behavior and Design, a background in both design and research is preferred, but students may come from a variety of disciplines.

Yes, HOWEVER, if substantial progress has not been made on their Master’s, then it’s a long shot. Applicants should be told the following two things: 1. Their Ph.D. work will take 4 years to complete, and 2. Lack of substantial progress on their Master’s Thesis will be viewed as a liability.

Yes. Note that GRE scores must be less than five years old. See the language proficiency requirement here

No. Academic letters of recommendation are valuable and somewhat preferable; however recommendations should be from people who can best assess the qualities, characteristics, and capabilities of the applicant. 

Cornell’s institutional test code for ETS is 2098. DEA’s department code is 4499.

D+EA recommends a combined verbal/quantitative GRE score of 310 (new scoring system effective November 2011) or a combined score of 1200 (old scoring) but this is not an absolute cutoff. Candidates with strong applications, but scores below this level, may be considered. You may submit scores to D+EA more than once if you re-take the test. Your scores may not be older than 5 years.
